Abstract
An aqueous color paint composition comprising PA0 (I) an aqueous dispersion of acrylic polymer fine particles, PA0 (II) a modified polyester resin aqueous dispersion obtained by neutralizing, with a basic substance, a modified polyester resin formed by polymerizing (A) a radical-polymerizable unsaturated group-containing polyester resin and (B) a mixture of an ethylenically unsaturated carboxylic acid and another copolymerizable unsaturated monomer and having an acid value of 8 to 200 and a hydroxyl value of 30 to 300, and dispersing the resulting resin in an aqueous dispersion medium, PA0 (III) a crosslinking agent, and PA0 (IV) a color pigment. The composition is, even if high-solid, good in coatability and excellent in smoothness of the coated film. It is therefore quite suitable as a high-solid base coat composition when coating an outside plate, etc. of automobiles, two-wheelers, electric appliances, etc. requiring beautiful appearance.
